Medtronic Recalls MiniMed Pumps Over Batteries
Medtronic is recalling (Class 1) its MiniMed Insulin pumps due to concerns about reduced battery life in certain situations. “Insulin pumps that have been dropped, bumped, or experienced physical impact may have damage to internal electrical components, which may cause reduced pump battery life,” a recall notice says. “Since the defect reduces the battery life overall, it shortens the time between low battery alarms and increases the frequency with which the user must insert a new battery… Early battery depletion could result in power loss and insulin delivery could be interrupted, resulting in under-delivery of insulin potentially leading to hyperglycemia and/or DKA [diabetic ketoacidosis].”
Last month, the company sent “safety alert” notices to customers and healthcare professionals telling them to always pay attention to alerts and alarms displayed on the pumps and advising them on when to replace the device batteries. FDA has determined the recall to be device design-related.
